We need to find the radius of the sphere

 

Surface area  =  4 * pi * r^2

 

113.04  = 4 * pi * r^2       divide both sides by 4 pi

 

113.04 / [ 4 pi]  =  r^2

 

√ [ 113.04/ [ 4pi] ]  = r

 

So...the volume is given by

 

(4/3) pi *  r^3

 

(4/3)pi * (√ [ 113.04/ [ 4pi] ])^3  =  

 

35.97 pi   in^3
